Procedure for Migration of Existing Billing Documents 

The evaluation of consumption data is based on the entries in the Consumption History table. If old print documents are to form part of the evaluation, you must generate corresponding DBERCHV records with the CONSHIST migration object for the upgrade to SAP IS-U 4.63 (or higher). See the documentation for the CONSHIST migration object. No bill lines are structured when this object is migrated. A “core document”, consisting of a document header (table ERCH) and consumption history (table DBERCHV) is created. You must populate the following fields during the migration, so that the BW DataSource can extract consumption values.
